There's a Sheraton Grand in Sacramento that hasn't made the list... Yet.
With regards to Starwood weeding out the overlapping Sheraton/Luxury Collection properties, the Sheraton in Kuwait City [for one; Addis Ababa is another] is an iconic hotel in that city and has always carried the Sheraton brand name despite being a member of the Luxury Collection for many years. I don't see it being pulled from the LC portfolio nor losing its name anytime soon. Maybe Starwood is making a few exceptions?
